PENCIL-SHAHPEN-Ea.

Specification of Letters Patent.

Application filed .April 5,1906. Serial ND. 309,781-

Be it known that I, PETER MAKIN, a citi-`l` zen of the United States, residing at Sparrows Point, in the county or Baltimore and State of Maryland, have invented new and useul Improvements in Pencil-Sharpeners, of which the following is a speciiication.

My invention relates to pencil-Sharpeners; and its rimary object is to provide a novel and highly-useful device of this character which is to be constructed from a single tubular member lwhich is provided with pairs of diverging slits of relatively diierent lengths to permit portions thereof to be bent inwardly toward each other to provide cutting-v blades. i

With the above and other objects in view the invention consists of the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, whereln* Figure 1 is a perspective of a pencil-sharpener constructed in accordance with my invention, the same being illustrated in applied position upon a pencil. 2 is longitudinal section on'the line 2 2 of Fig. 1, and Fig. 3 is a' transverse section on the line 3 3 of Fig. 2.

Referring tothe drawings by reference-numerals, 1 designates the tubular member, which has an interior diameter a little greater than the'exterior diameter of the pencil to snugly receive the end of the pencil. The member is provided with pairs of slits, the

slits of each pair being of relatively diierent lengths and communicating with and diverging from each other to permit portions of the member to be bent inwardly toward each other to rovide a plurality of cutting-blades having tllnieir cutting edges arranged at an angle and in an annular plane relative to the longitudinal axis oi the member, whereby the most advantageous results may be attained.

Inasmuch as the cutting edges of the blades are arranged at an angle and in an annular plane relative to the longitudinal axisA of the member, a draw-cut may be produced when a rotary and rearward motion is imparted to the member, thus obviating the objections to the well-known encil-sharpeners-namely,

lthat of cutting directly against the grain of the wood, producing a rough cut, rendering itv difficult to force the blade through the wood and breaking the lead.

The encil-sharpener is to be carried upon a penci and is to carry a rubber 4, which is positioned in its outer end. The outer end of the member is serrated to provide flexible portions 5, which are to be bent to engage the rubber 4; to secure the same in applied position.

In the use of my improved pencil-sharpener both ends of the pencil may be sharpened and. the Sharpener applied over one of the sharprened ends of thepencil to protect vthe lead om injury and to retain the rubber 1n position for ready use. In view of the i'act that the cutting edges of the blades are arranged at an angle and in an annular plane relative to the longitudinal axis of the member the blades snugly receive one of the sharpened ends of the pencil, and thus protect the lead from injury.

Having fully described and illustrated my invention, what I claim isj 1. A encil-sharpener comprising a tubue lar mein er provided with a pair of diverging slits of' comparatively diiierent lengths to permit a portion of the member to be bent inwardly to provide a cutting-blade.

2. A pencil-Sharpener comprising a tubular member provided with pairs oi' slits, the slits of each pair being of relatively different lengths and communicating with and diverging from each other to permit portions of the member to be bent inwardly to' provide blades having their cutting edges arranged at an angleand in an annular plane with relation to the longitudinal axis of the member.

In testimonyvwhereof I ailix my signature in presence of Itwo witnesses.
